The percentage of flatfoot is higher among preschool developmental delay children than those normal ones. However, the reason which causes most of the developmental delay cases are unknown and such developmental delay case with flatfoot is not discussed either.
Footprint Parameter Analysis is frequently to be used as a convenient tool to show foot arch height. Such analysis is to evaluate the level of flat foot in clinical usage and regarded as the easiest tool to be applied. Nevertheless, the research of footprint parameter analysis on developmental delay children is relatively rare.
Evidence base medicine shows flatfoot is easily to cause pain and functional disability. Foot type and some correlation research of activities are popular topics to be discussed. It’s straightly showed the correlation of children’s static standing stance when measuring the balance control by Single-leg stance. This research use Biodex Balance System (BBS) to test static balance reaction. The pathway of anterior/posterior from the center of gravity and pathway of left/right from the center of gravity on overall pathway which mean Stability Index will show balance reaction ability and provide the data of static standing balance for those unknown reason developmental delay children.
Current researches show children’s foot arch height will influence static standing balance performance. However, there is no research on the foot arch height of unknown reason developmental delay children and correlation of static standing balance. The subjects of this experiment are 30 children of 5-6 year old which are diagnosed as unknown reason developmental delay. There is no disorder of musculoskeletal, neural system or other medicine problems on each subject. In addition, the subjects have no sprain or other foot disorders before 6 months. The development of cognition function and motor function on such developmental delay children can help to do footprint parameter analysis. Subjects need to maintain single-leg stance at least for 10 seconds. The children with above abilities which can go through each step are subjects of this experiment.
This experiment use the result data of Clarke’s angle in footprint parameter analysis to evaluate the foot arch height and BBS measures the COP moving pathway of single-leg stance. These values discover the correlation between foot arch height and control ability of static standing balance on developmental delay children.
The main purpose of this research are:
1. To check the correlation between the pathway of anterior/posterior from the center of gravity and pathway of left/right from the center of gravity on overall pathway when the developmental delay children use single-leg stance.
2. To check the foot arch height and single-leg stance on correlation between the pathway of anterior/posterior from the center of gravity and pathway of left/right from the center of gravity on overall pathway when the developmental delay children finished footprint parameter analysis.
This research data used SPSS 17.0 Chinese version to process analysis. The statistic methods are Descriptive statistics and Pearson Correlation Test and Independent-Samples T Test.
The experiment of this research shown that:
1. The pathway of left/right from the center of gravity can represent the overall pathway when doing single-leg static standing balance test.
2. It’s irrelevant between foot arch height and static balance reaction of developmental delay children.
Due to there is no Stability Index of normal children to be comparisons, we can’t find out whether it’s good or bad on the static balance control ability of developmental delay children. How the static balance control ability influence the developmental delay children’s plantar cutaneous somatosensation is still unknow. Due to the limit of sampling, it is necessary to cautious when making conclusion of test result.
